Unfortunately, our perception of bias is heavily influenced by our personal biases. My recollection of the Bush years was very different, the anti-Bush sentiment are much more prominent in my mind. It would be an interesting technology project or site. Do a sentiment analysis of major media sources. Search for how often a particular phrase is used. e.g. Immigration: "Illegal Alien" or "Undocumented Worker" Abortion: "Pro-Life" or "Anti-Abortion" Something that could update in real time. It is unavoidable that every news site will have some slant, but an objective number based on rational criteria would be a good tool ala the nutrition facts labels on food packages.
